recense 8 needles and the bottoms of the grooves in which they arelocated, this friction in devices of this character as heretofore madecausing rapid Wear of the bottoms ot' the grooves and the upper end ofthe needlecylinder. This Wearing caused change in the directions ofmovements of the needles, which resulted in causing the needles to missloops and form a poor fabric and in other detrimental results.

By means of my improved hardened bearing-ring, which is positioned atthe upper end of the needle-cylinder, the life of the parte is verymaterially lengthened and a better fabric is obtained, and furthermore,breaking of the needles due to their distortion 1n machines aspreviously constructed is avoided by maintaining trie needles in theirtrue lines or' movement. ln case Wear of the bearing-ring does takeplace, the ring is readily shifted for presentingdifferent peripheralsurfaces to the needles, the only part. requiring renewal in any eventlbeing this single hardened steel bearing-ring. rlhe bearing-ring hasthe. further advantage that by its use the needles are maintained intheir proper lines of travel Vtor register ing accurately with thequills et the usual transfer-quill head employed in making' ribbed endsof half-hose.

The upper end of the bearing-ring further .terms a bearing-surface 97ttor the .levver edges ci the sinkers for maintaining the sinkers intheir true lines ottravel. The bearing-ring is located in the anglebetween the paths et' movements of the needles and sinkers. My improveddevice therefore provides means whereby both the sinkers and the needlesare maintained in their true linesl of travel for produeinga superiorfabric and preventing excessive wear of the parts,

My improved device has the ifurther advantage th :it the ends ot thesinkers are arranged to pass entirely through their radial bearing-slotsin both directions, these. radial slots being open at their inner andouiL r r "s, the etl'ect being that the sinks nia-intein the slats clearlint "ing ifuil and'clear nuwe-ments of the halters, l

dill represents the usual guard and thread' guide, which is pivoted tothe post 74 on a hinge 102 and is arranged te be thrown backwardly awayfrom the sinkers and needles. -t is pro vided with a thread slot- 103connecting with a thread'hole 'l0-i, at which point the thread is'guided to the needles in usual manner.

l provide a hold-down device 107, which directs the fabric immediatelyafter being formed, in the proper direction, inte the interior of theneedle-cylinder for directing it away from the needles and sinkerswithout strain either upon the fabric or upon the sinkers or needles,and in such manner as to maintain all parts of the knitting line. inproper relation with the needles and sinkers.l This hold-down deviceacts in adjacencv to the knitting line. 1T

l have shown the holdloivn device in the form of a roller 108 on ashaft'jrOQ onflh. depending arm 110 secured to the guard andthread-guide 101, as by means of a screw lll. This roller is preferablya frustoconical roller extending crosswise of the knitting` line withits end of larger diameter extending` outwardly and tapering toward itsinner end. Itacts tov roll the fabric being formed curve-like into theneedleecylinder.

Having thus fully described my invention, what l claim as new and desireto secure by Letters Patent, is:

In a, circular knitting machine, the combination of knittinginstrumentalities annularly arranged in a closed path, a camring and athread-ring connected together for combined rotation, means for rotatingSaid rings, means including said cam-ring for actuating said knittinginstrumentalities for forming a knitting line having a knitting Wavetherein, an arm secured to said thread-ring and having a dependingportion spaced therefrom depending into the space within saidthread-ring', the upper ends of the knitting instrumentalitiesreciprocating up and down in the space between said thread-ring and saiddepending ,portion of said arm, a truste-conical holddown roll of 1greater Alength than average diameter journaled on said arm in ahorizontal plane having its larger end adjacent to said knitting linewith the periphery of said roll receding from the horizontal plane inwhich said knitting line is-located toward the middle portion of saidthreadring, to cause upward bulging of the knitcf knitted fabric towardthe middle of Said closed path, and means for swinging said andknitting-line.

in testimony whereof, I have hereunto ted fabric adjacent said knittingWave and downward curving of said bulged4 portalen' signed my name inthe presence of two subscribing Witnesses.
